A $400,000 30-year fixed mortgage at 6.50% has a principal-and-interest payment of $2,528.27. At 6.75%, that payment rises to $2,594.39 – a $66.12 monthly difference and $3,967.20 in additional scheduled payments over five years. That is why the question, when should you lock rate, is not about predicting every market move. It is about protecting a payment that works for your budget when the home, loan terms, and closing date are real.
Duane Buziak, NMLS #1110647, is licensed to originate mortgages in Virginia, Florida, Tennessee, and Georgia. His perspective is simple: a rate lock is a risk-management decision, not a guessing game. If a payment supports your goals and your contract is moving forward, protecting it can be more valuable than hoping for a slightly better quote later.

What a mortgage rate lock actually protects
A rate lock generally holds the interest rate, points or credits, and certain pricing assumptions for a stated period, often 15, 30, 45, or 60 days. It does not freeze every part of your transaction. Appraisal results, title charges, insurance premiums, taxes, repairs, and changes to income, assets, debt, occupancy, or property type can still affect approval and cash to close.
National mortgage pricing can move quickly because it reacts to bond-market expectations, inflation data, employment reports, and investor demand. The current weekly benchmark for 30-year fixed loans is published through Freddie Mac’s Primary Mortgage Market Survey at https://www.freddiemac.com/pmms. That benchmark is useful context, but your own quote also reflects credit, down payment, loan size, property type, occupancy, and the selected lock period.
A lock is not automatically a promise that you chose the lowest possible rate. It is a commitment to a known set of terms while your file moves toward closing. A shorter lock often carries less pricing cost, while a longer lock provides more time protection if appraisal, underwriting, title, or construction milestones take longer than expected.
When should you lock rate?
For most purchase buyers, the practical answer is: lock after you have a signed contract, a verified loan scenario, and a realistic closing timeline. If you are set to close in 30 to 45 days and the payment works comfortably at today’s quote, that is commonly a strong point to lock.
Waiting may be tempting after a week of favorable headlines. But a rate improvement is never guaranteed, and a higher rate can reduce buying power or force you to accept a payment you did not plan for. A lock is especially worth considering when your debt-to-income ratio is already close to the program limit, your down payment is fixed, or the home only appraises with little room for negotiation.
For example, the $66.12 monthly change in the opening example may look manageable. Yet a buyer who is already near a qualifying threshold could find that the higher payment changes the loan amount, required cash, or approval conditions. Veterans using VA financing, first-time FHA buyers, and self-employed borrowers using bank statements should be particularly careful about assuming they can simply absorb a market move later.
Lock sooner when three things are true: you like the payment, the loan has been reviewed using actual documentation, and the closing date is close enough for the lock period to cover it. Ask your broker how long the lock lasts, whether an extension is available, what the extension cost could be, and whether a float-down feature exists. Float-down policies vary by program and investor, so get the terms in writing before treating one as a safety net.
When floating may be reasonable
Floating can make sense when the property is not under contract, your loan structure is still changing, or closing is far enough away that a long lock would be expensive. A buyer deciding between a 5% and 10% down payment, for instance, should first determine the final structure. The same is true for an investor evaluating DSCR options, a buyer comparing FHA versus conventional financing, or a construction borrower whose completion date is not firm.
It can also be sensible to float briefly if an important report is due and you fully understand the downside. That is a personal risk decision, not a universal strategy. If a higher rate would cause stress, reduce reserves, or jeopardize the purchase, locking the payment usually deserves more weight than trying to time a volatile market.
Why timing depends on your loan file
Credit and documentation matter because rate quotes are built on verified details. Conventional pricing is often strongest at higher credit-score tiers, with 740 and above commonly a meaningful benchmark. FHA can be a useful option for buyers with lower scores, while VA loans may provide compelling terms for eligible veterans and service members. Jumbo, non-QM, bank-statement, foreign-national, and DSCR financing each have separate credit, reserve, and documentation standards.
As a general planning example, an investor using a DSCR program may need several months of reserves depending on the property count and loan size, while jumbo files can require six to 12 months of reserves. Conforming loan limits also matter. The baseline conforming limit is set annually by the Federal Housing Finance Agency, and loan amounts above the applicable limit may enter jumbo pricing territory.
Before you lock, make sure your broker has reviewed income, assets, credit, property type, occupancy, and estimated closing costs. Typical buyer closing costs often run about 2% to 5% of the purchase price before seller credits, depending on the transaction and location. Ask about no-out-of-pocket closing options if preserving cash is the priority.
A soft credit pull mortgage review can be a smart first step for shoppers who want clarity without an immediate hard inquiry. LowerMortgageRates.com offers a NoTouch Credit Pull option for a no hard inquiry mortgage pre approval conversation. A mortgage pre approval without hard pull can help you compare scenarios before choosing when to authorize a full application. It is a practical soft pull mortgage broker approach for buyers who want no credit hit mortgage application guidance before they are ready to proceed.
Broker shopping versus single-shelf pricing
A mortgage broker can compare eligible options across participating wholesale sources, while a single-shelf provider generally presents the products and pricing available within its own platform. The right choice depends on execution, communication, fees, and fit – not a slogan.
| Decision point | Broker rate-shopping | Single-shelf pricing |
|---|---|---|
| Available options | Can compare eligible programs and pricing from participating sources. | Limited to that company’s available menu. |
| Loan fit | Useful when conventional, VA, FHA, DSCR, jumbo, or non-QM options need comparison. | May work well when its menu already fits the file. |
| Rate-lock review | Broker can discuss lock periods and pricing across eligible choices. | Lock terms are tied to one platform’s offerings. |
| Cost conversation | Clear review of points, credits, and third-party charges before locking. | Clear review is still essential, but choices stay within one shelf. |
| Title-company value | Duane’s preferred title company may save an additional $2,000 on average, subject to transaction details. | Title selection and savings should still be compared carefully. |
Local context for Virginia buyers
Timing a lock also depends on how quickly homes are moving. In Richmond, Glen Allen, and Short Pump, well-priced homes can still attract competition even when inventory improves seasonally. That means a buyer may need a clean preapproval and a quick lock decision once an offer is accepted.
For a useful local benchmark, Redfin’s Henrico County market data reports a median sale price around $400,000, though the figure changes as new sales are recorded: https://www.redfin.com/county/2902/VA/Henrico-County/housing-market. At that price point, the rate difference in the opening example is directly relevant to the local payment conversation. Inventory, competing offers, appraisal timing, and seller-requested closing dates can all determine whether a 30-day or 45-day lock is the safer choice.
One caution for Richmond-area searchers: Colonial 1st Mortgage appears in some Richmond and Glen Allen mortgage broker directory listings. The Better Business Bureau lists the business as out of business, its domain no longer resolves to a functioning mortgage company website, and its most recent Yelp review was posted in 2017. Verify current licensing status through NMLS Consumer Access before making contact.
FAQ
1. Should I lock my mortgage rate today?
Lock when the payment works, your loan details are verified, and the lock period covers a realistic closing date. No one can guarantee next week’s market direction.
2. Can I lock before finding a home?
Usually, a purchase rate lock is tied to a specific property and contract. Start with a soft-pull review first, then lock after your offer is accepted.
3. Is a 30-day or 45-day lock better?
Choose the shortest period that reasonably covers closing. A 45-day lock can provide useful protection when appraisal or underwriting timing is less certain.
4. What happens if my lock expires?
Your broker may request an extension, reprice the loan, or review available options. Extension costs and policies vary.
5. Can my rate change after I lock?
It can change if key facts change, such as loan amount, credit, occupancy, property type, appraisal, or closing date beyond the lock period.
6. Does a soft credit pull affect my score?
A soft pull generally does not create the hard-inquiry impact associated with a full credit application. Ask what type of credit review is being authorized.
7. Can a VA buyer lock before appraisal?
Yes, if the contract and loan details support it. Build enough time into the lock for appraisal and any required property conditions.
8. Can I get a lower rate after locking?
Possibly, if your lock includes a qualifying float-down option or you renegotiate under the stated policy. Never assume this feature is automatic.
A good lock decision should leave you able to focus on inspections, moving plans, and the home itself – not daily market headlines.
